(ii) Removal of Restrictions on Restricted Units. Upon or as soon as reasonably practicable following the lapse of all forfeiture restrictions with respect to each Unit Award, the Participant shall be entitled to have the restrictions removed from his or her Management Holdings Unit certificate (or book-entry account, as applicable) so that the Participant then holds an unrestricted Management Holdings Unit (and any corresponding restrictions shall be removed from the corresponding GP Unit held by Management Holdings), provided that an unrestricted Unit may remain subject to such terms and conditions as may be set forth in an applicable Award Agreement, including, without limitation, repurchase, transfer or other restrictions or limitations.

-6-

otherwise based on or related to GP Units and/or Management Holdings Units or other securities of Southcross GP or Management Holdings, in whole or in part. The Committee shall determine the terms and conditions of any Other Unit-Based Award. Upon or following the vesting or lapse of forfeiture or other restrictions, an Other Unit-Based Award may be paid in cash, GP Units and/or Management Holdings Units (including Unit Awards that may be subject to such forfeiture or other terms and conditions as may be established by the Committee), or any combination thereof, as provided in the Award Agreement.

(c) General.

(i) Forfeitures. Except as otherwise provided in the terms of an Award Agreement, upon termination of a Participant’s Service for any reason during an applicable Restricted Period, all outstanding awards held by such Participant (and Awards corresponding thereto), to the extent then subject to forfeiture, shall be automatically forfeited. The Committee may, in its discretion, waive in whole or in part such forfeiture with respect to any such Award.

(ii) Awards May Be Granted Separately or Together. Awards may, in the discretion of the Committee, be granted either alone or in addition to, in tandem with, or in substitution for any other Award granted under the Plan or any award granted under any other plan of the Company or any Affiliate, provided however that each Downstairs Award shall be granted in tandem with a corresponding Upstairs Award covering an equivalent number of Units and each Upstairs Award shall be granted in tandem with a corresponding Downstairs Award covering an equivalent number of Units. Awards granted in addition to or in tandem with other Awards or awards granted under any other plan of the Company or any Affiliate may be granted either at the same time as or at a different time from the grant of such other Awards or awards.

(iii) Limits on Transfer of Awards. Except as may be permitted by the terms of the Limited Liability Company Agreement, no Award and no right under any such Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant other than by will or the laws of descent and distribution and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable against the Company or any Affiliate.

(v) Consideration for Grants. To the extent permitted by applicable law, Awards may be granted for such consideration, including services, as the Committee shall determine.

(vi) Delivery of Units or other Securities and Payment by Participant of Consideration. Notwithstanding anything in the Plan or any Award Agreement to the contrary, subject to compliance with Section 409A, the Company shall not be required to issue or deliver any certificates or make any book entries evidencing Units in connection with any Award, unless and until the Board or the Committee has determined that the issuance of such securities is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any securities exchange on which the securities are listed or traded, and the securities are covered by an effective registration statement or applicable exemption from registration. In addition to the terms and conditions provided herein, the Board or the Committee may require that a Participant make such reasonable covenants, agreements, and representations as the Board or the Committee, in its discretion, deems advisable in order to comply with any such laws, regulations, or requirements. Without limiting the generality of the foregoing, the delivery of Units in connection with an Award may be deferred for any period during which, in the good faith determination of the Committee, the Company is not reasonably able to obtain or deliver Units pursuant to such Award without violating applicable law or the applicable rules or regulations of any governmental agency or authority or securities exchange. No Units or other securities shall be delivered pursuant to any Award until payment in full of any amount required to be paid pursuant to the Plan or the applicable Award Agreement is received by the Company.

(b) Amendments to Awards. Subject to Section 7(a) above, the Committee may waive any conditions or rights under, amend any terms of, or alter any Award theretofore granted, provided that no change, other than pursuant to Section 4(b) above or 7(c) below, in any Award shall materially reduce the rights or benefits of a Participant with respect to an Award without the consent of such Participant.

-8-

(c) Actions Upon the Occurrence of Certain Events. Upon the occurrence of a Change in Control, any transaction or event described in Section 4(b) above, any change in applicable laws or regulations affecting the Plan or Awards hereunder, or any change in accounting principles affecting the financial statements of the Company or the Partnership, the Committee, in its sole discretion, without the consent of any Participant or holder of an Award, and on such terms and conditions as it deems appropriate, may take any one or more of the following actions:

(i) provide for either (A) the termination or cancellation of any Award in exchange for a payment in an amount, if any, equal to the amount that would have been attained upon the exercise of such Award or realization of the Participant’s rights under such Award (which, with respect to a Unit Award shall be the Fair Market Value of the applicable Unit), and, for the avoidance of doubt, if as of the date of the occurrence of such transaction or event, the Committee determines in good faith that no amount would have been payable upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company without payment or (B) the replacement of such Award with other rights or property selected by the Committee in its sole discretion having an aggregate value not exceeding the amount that could have been attained upon the exercise of such Award or realization of the Participant’s rights had such Award been currently exercisable or payable or fully vested;

SECTION 8. General Provisions.

(a) No Rights to Award. No Person shall have any claim to be granted any Award under the Plan, and there is no obligation for uniformity of treatment of Participants, including the treatment upon termination of Service. The terms and conditions of Awards need not be the same with respect to each recipient.

(b) Tax Withholding.

-9-

to such Award or other property) of any applicable taxes payable in respect of an Award, including its grant, its exercise, the lapse of restrictions thereon, or any payment or transfer thereunder or under the Plan, and to take such other action as may be necessary in the opinion of the Company to satisfy its withholding obligations for the payment of such taxes. In the event that Units that would otherwise be issued pursuant to an Award are used to satisfy such withholding obligations, the number of Units which may be so withheld or surrendered shall be limited to the number of Units which have a Fair Market Value on the date of withholding equal to the aggregate amount of such liabilities based on the minimum statutory withholding rates for federal, state, local and foreign income tax and payroll tax purposes that are applicable to such supplemental taxable income.

(c) No Right to Employment or Services. The grant of an Award shall not be construed as giving a Participant the right to be retained in the employ of Southcross GP or any of its Affiliates, continue consulting services or to remain on the Board, as applicable. Furthermore, Southcross GP or one of its Affiliates may at any time dismiss a Participant from employment or consulting free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan, any Award Agreement or other written agreement between any such entity and the Participant.

To the extent applicable, the Plan and Award Agreements shall be interpreted in accordance with Section 409A. Notwithstanding any provision of the Plan to the contrary, in the event that following the Effective Date (as defined in Section 9 below), the Committee determines that any Award may be subject to Section 409A, the Committee may adopt such amendments to the Plan and the applicable Award Agreement, adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), and/or take any other actions that the Committee determines are necessary or appropriate to preserve the intended tax treatment of the Award, including without limitation, actions intended to (i) exempt the Award from Section 409A, or (ii) comply with the requirements of Section 409A; provided, however, that nothing herein shall create any obligation on the part of the Committee or the Company or any of its Affiliates to adopt any such amendment, policy or procedure or take any such other action, nor shall the Committee or the Company or any of its Affiliates have any liability for failing to do so. Notwithstanding any provision in the Plan to the contrary, the time of payment with respect to any Award that is subject to Section 409A shall not be accelerated, except as permitted under Treasury Regulation Section 1.409A-3(j)(4) or other applicable regulatory guidance.

(e) Compliance with Laws. The Plan, the granting of and lapse of forfeiture restrictions with respect to Awards under the Plan and the issuance and delivery of Units and the payment of money under the Plan or under Awards granted or awarded hereunder are subject to compliance with all applicable federal, state, local and foreign laws, rules and regulations (including but not limited to state, federal and foreign securities law and margin requirements), the rules of any securities exchange or automated quotation system on which the Units are listed, quoted or traded, and to such approvals by any listing, regulatory or governmental authority as may be necessary or advisable in connection therewith. Any securities delivered under the Plan

-10-

shall be subject to such restrictions, and the Person acquiring such securities shall, if requested by the Company, provide such assurances and representations to the Company as the Company may deem necessary or desirable to assure compliance with all applicable legal requirements. To the extent permitted by applicable law, the Plan and Awards granted or awarded hereunder shall be deemed amended to the extent necessary to conform to such laws, rules and regulations. In the event an Award is granted to or held by a Participant who is employed or providing services outside the United States, the Committee may, in its sole discretion, modify the provisions of the Plan or of such Award as they pertain to such Participant to comply with applicable foreign law or to recognize differences in local law, currency or tax policy. The Committee may also impose conditions on the grant, issuance, exercise, lapse of forfeiture restrictions, settlement or retention of Awards in order to comply with such foreign law and/or to minimize the Company’s obligations with respect to tax equalization for Participants employed outside their home country.

(f) Governing Law. The validity, construction, and effect of the Plan and any rules and regulations relating to the Plan shall be determined in accordance with the laws of the State of Delaware without regard to its conflicts of laws principles.

(g) Severability. If any provision of the Plan or any Award is or becomes, or is deemed to be, invalid, illegal, or unenforceable in any jurisdiction or as to any Person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to the applicable law or, if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction, Person or Award and the remainder of the Plan and any such Award shall remain in full force and effect.

(h) Other Laws. The Committee may refuse to issue or transfer any Units or other consideration under an Award if, in its sole discretion, it determines that the issuance or transfer of such Units or such other consideration might violate any applicable law or regulation, the rules of the principal securities exchange on which the Units are then traded, or entitle the Company or an Affiliate to recover the same under Section 16(b) of the Exchange Act, and any payment tendered to the Company by a Participant, other holder or beneficiary in connection with the exercise of such Award shall be promptly refunded to the relevant Participant, holder or beneficiary.

(i) No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any of its Affiliates, on the one hand, and a Participant or any other Person, on the other hand. To the extent that any Person acquires a right to receive payments pursuant to an Award, such right shall be no greater than the right of any general unsecured creditor of the Company or any participating Affiliate of the Company.

(j) No Fractional Units. Unless otherwise determined by the Committee, no fractional Units shall be issued or delivered pursuant to the Plan or any Award, and the Committee shall determine whether cash, other securities, or other property shall be paid or transferred in lieu of any fractional Units or whether such fractional Units or any rights thereto shall be canceled, terminated, or otherwise eliminated.

(k) Headings. Headings are given to the Sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision hereof.

(l) No Guarantee of Tax Consequences. None of the Board, the Committee or the Company or any Affiliate thereof (or any employee or officer of the Company or any Affiliate) provides or has provided any tax advice to any Participant or any other Person or makes or has made any assurance, commitment or guarantee that any federal, state or local tax treatment will (or will not) apply or be available to any Participant or other Person.

(m) Clawback; Misconduct. To the extent required by applicable law or any applicable securities exchange listing standards, Awards and amounts paid or payable pursuant to or with respect to Awards shall be subject to clawback as determined by the Committee, which clawback may include forfeiture, repurchase and/or recoupment of Awards and amounts paid or payable pursuant to or with respect to Awards. In addition, and without limiting the foregoing, except as otherwise provided by the Committee, if at any time (including after an award has vested) the Committee or any person designated by the Committee (each such person, an “Authorized Officer”) reasonably believes that a Participant may have committed an Act of Misconduct as described in this Section 8(m), the Authorized Officer, the Committee or the Board may suspend the Participant’s rights to exercise or to vest in an Award, and/or to receive payment for or receive Units in settlement of an Award pending a determination of whether an Act of Misconduct has been committed.

If the Committee or an Authorized Officer determines that a Participant has committed an act of embezzlement, fraud, dishonesty, nonpayment of any obligation owed to the Company or any Affiliate of the Company, breach of fiduciary duty, violation of ethics policy or code of conduct, or deliberate disregard of the Company’s or Affiliate of the Company’s rules resulting in loss, damage or injury to the Company or any Affiliate of the Company, or if a Participant makes an unauthorized disclosure of any trade secret or confidential information, solicits any Employee or other service provider to leave the employ or cease providing services to the Company or any Affiliate of the Company, breaches any intellectual property or assignment of inventions covenant, engages in any conduct constituting unfair competition, breaches any non-competition agreement, induces any customer to breach a contract with the Company or any Affiliate of the Company or to cease doing business with the Company or any Affiliate of the Company, or induces any principal for whom the Company or any Affiliate of the Company acts as agent to terminate such agency relationship (any of the foregoing acts, an “Act of Misconduct”), then except as otherwise provided by the Committee, (i) neither the Participant nor his or her estate nor transferee shall be entitled to vest in or have the restrictions on an Award lapse, or otherwise receive any payment in respect of an Award, (ii) the Participant will forfeit all outstanding Awards and (iii) the Participant may be required, at the Committee’s sole discretion, to return and/or repay to the Company any then vested Units previously granted under the Plan.

-12-

(n) Facility Payment. Any amounts payable hereunder to any Person under legal disability or who, in the judgment of the Committee, is unable to manage properly his or her financial affairs, may be paid to the legal representative of such Person, or may be applied for the benefit of such Person in any manner that the Committee may select, and the Company its Affiliates shall be relieved of any further liability for payment of such amounts.

(ii) The Company (or its assignee) shall exercise the Call Right (if so elected) by written notice to Participant (and/or, if applicable, any permitted transferees) within the Repurchase Period, specifying a date within such period on which the Call Right shall be exercised and the number of Units as to which the Call Right is being exercised. Upon such notification, the Participant and any permitted transferees shall promptly surrender to the Company (or its assignee) any certificates or other documents representing the Units being purchased, free and clear of any liens or encumbrances. Except as provided below, upon the Company’s (or its assignee’s) receipt of any such certificates or documents from the Participant or any permitted transferees, the Company (or its assignee) shall deliver to him, her or them payment of the Repurchase Price (as defined below) for the Units being purchased.

(b) [Company Repurchase Obligation.

(i) In the event the Participant’s Service terminates as a result of the Participant’s resignation for Good Reason (as defined below) and the Units are not listed on a national securities exchange or a national inter-dealer quotation system (or are not otherwise publicly tradable), then during the Repurchase Period, the Participant shall have the option (the “Put Right”) to cause the Company or one of its Affiliates to repurchase all, but not less than all, of the Participant’s vested Units, provided, however, that the Put Right shall be subject to the Committee’s good faith determination that the Company and its Affiliates possess sufficient liquidity at the applicable time such that the Put Right will not have a material negative impact on the operations or financial position of the Company and its Affiliates.

(ii) The Participant shall exercise the Put Right (if so elected) by written notice to the Company within the Repurchase Period (and before the 30^th day prior to the expiration of the Repurchase Period), specifying a date more than 30 days after the date of such written notice and within the Repurchase Period on which the Put Right shall be exercised. Upon the time of such repurchase, the Participant and any permitted transferees shall promptly surrender to the Company any certificates or other documents representing the Units being purchased, free and clear of any liens or encumbrances. Except as provided below, upon the Company’s receipt of any such certificates or documents from the Participant or any permitted transferees, the Company shall deliver to him, her or them payment of the Repurchase Price for the Units.

(iii) For purposes of this Agreement, “Good Reason” means the occurrence of one or more of the following actions by Southcross GP or its Affiliates without the Participant’s consent: (1) a material reduction in the duties and responsibilities held by the Participant, except in connection with a termination of the Participant’s Service for Cause; (2) a material reduction in the Participant’s base salary or guideline (target) bonus; or (3) a material change in the geographic location at which the Participant must perform services for Southcross GP or its Affiliates; provided, however, that no termination of Service by the Participant shall constitute a termination for Good Reason unless (a) the Participant has first provided Southcross GP with written notice specifically identifying the acts or omissions constituting the grounds for Good Reason within thirty (30) days after the Participant has or should reasonably be expected to have had knowledge of the occurrence thereof, (b) Southcross GP has not cured such acts or omissions within thirty (30) days of its actual receipt of such notice, and (c) the effective date of the Participant’s termination for Good Reason occurs no later than ninety (90) days after the initial existence of the facts or circumstances constituting Good Reason.]¹

Any payment under this Section 5 that would cause such violation or default shall result in an extension of the Repurchase Period, in the sole discretion of the Committee, until thirty days after the date such payment shall no longer cause any such violation or default and at which time the Call Right or Put Right, as applicable, may be exercised with the Repurchase Price calculated as of the date the Call Right or Put Right is actually exercised.
